The primary aim of this investigation was to determine which cycling training device, Rollers or Trainers, was most effective in improving 10-km time trial. Eight male and 6 female volunteers (N = 14; age = 23.6 ± 4.6 yrs; height = 172.7 ± 9.9 cm; body mass = 68.4 ± 10.4 kg; % body fat = 16.9 ± 7.7; VO = 61.0 ± 9.4 ml·kg·min) provided informed consent prior to participation. Participants performed a10-km time trial at baseline and were then randomly assigned into one of three groups: Rollers (R), Trainers (T), or Control (C). Participants assigned to the R or T groups attended 24 supervised workout sessions throughout an 8-wk period (F: 3 days/week; I: 65-80% HR; D: 40 min; M: R or T). There were no significant differences in baseline 10-km time trial between R, T, and C groups [F(2,12) = 0.34, p = .72]. There was a significant difference in 10-km time trial improvement between groups post-assessment when controlling for baseline values (F = 17.04, p <.001). R participants improved by 20.4s [t(4) = 4.86, p = .008] and T participants improved by 12.8s [t(4) = 4.57, p = .01], while there was no significant improvement for subjects in C. Participants using R and T displayed significant decrements in time with respect to the 10-km time trial. However, R had a greater improvement in 10-km time trial when compared to T.
本研究的主要目的是确定哪种骑行训练设备，即滚筒训练器还是固定训练器，在提高10公里计时赛成绩方面最有效。8名男性和6名女性志愿者（N = 14；年龄 = 23.6 ± 4.6岁；身高 = 172.7 ± 9.9厘米；体重 = 68.4 ± 10.4千克；体脂百分比 = 16.9 ± 7.7；VO = 61.0 ± 9.4毫升·千克·分钟）在参与前提供了知情同意书。参与者在基线时进行了一次10公里计时赛，然后被随机分为三组之一：滚筒训练器组（R）、固定训练器组（T）或对照组（C）。分配到R组或T组的参与者在8周的时间里参加了24次有监督的训练课程（频率：每周3天；强度：心率的65 - 80%；持续时间：40分钟；训练方式：R或T）。R组、T组和C组在基线10公里计时赛成绩上没有显著差异[F(2,12) = 0.34，p = 0.72]。在控制基线值后，评估后各组之间在10公里计时赛成绩提高方面存在显著差异（F = 17.04，p < 0.001）。R组参与者成绩提高了20.4秒[t(4) = 4.86，p = 0.008]，T组参与者成绩提高了12.8秒[t(4) = 4.57，p = 0.01]，而C组受试者没有显著提高。使用R和T的参与者在10公里计时赛中的时间有显著减少。然而，与T组相比，R组在10公里计时赛中有更大的提高。
